FIELD OF THE INVENTION

The present invention relates in general to digital data networks and,more particularly, to network access and to minimizing unauthorizedinterception of data and denial of network services.

BACKGROUND OF THE INVENTION

There are many networks of computers throughout the world and there is aneed for the computers to communicate with each other across thenetwork. To provide order and security, many networks require a computerwishing access to be authenticated before that computer is grantedaccess. After establishing that the computer should be allowed tocommunicate over the network, it may be given an identification numberso that the computer may be contacted by other computers on the networkin accordance with network protocol. In general this process applies toa system designated as the Internet.

The Internet comprises a network of computers that interconnect many ofthe world's businesses, institutions, and individuals. The Internet,which means interconnected network of networks, links tens of thousandsof smaller computer networks.

The Internet can be accessed directly through telephone lines with adevice called a modem or indirectly though a local area network (LAN).Most users do not have the expertise to connect their computers andassociated equipment to the Internet and/or finances to have acontinuous connection to the Internet. Thus most users access theInternet through an Internet Service Provider (ISP). The ISP candistribute the costs of necessary equipment and telephone lines to manyusers on some time multiplexed basis. While an ISP may have access toonly one server and a few modems for receiving incoming calls fromusers, some ISPs have access to hundreds and even thousands of modemsand many servers to interface between users and one or more high speedtelephone lines of at least DSl standard communication capacity.

Usually the ISPs that charge the lowest prices to the user are thebusiest and users often find that access to a low cost ISP is blocked bya “busy signal”. On the other hand, a user of the high priced ISPsseldom encounters busy signals. The high priced ISPs have fewercustomers, can afford to add modems as needed and are not confrontedwith suddenly increased demands on equipment capacity.

Some ISPs use less expensive (i.e. slower rate, poorer quality or lowercapacity) telephone lines or equipment to provide low cost and as aresult the data transmission rate of communications between the user andthe Internet may be substantially less than the capability of the usersmodem. Many sets of information on the Internet, such as Web pages,include pictures, pointers to other pages, music etc, that require largeamounts of data to be transmitted for ultimate display. When a user isattempting to access material requiring the transmission of largevolumes of data, a low data transmission rate equates to a long timespent waiting to obtain that data.

When a user first installs software in a computer to be used inconnecting the computer to a given ISP, many items of information needto be provided to the software before the user can communicate with theISP and be connected to the Internet. While some of the information suchas the specific communication port to be used (i.e. com1 or com2) andthe modem type used in the computer would be universal and would beidentical regardless of the ISP used, other information is ISP specific.ISP specific type information would include the ISP dial-in number, aPassword Authentication Protocol (PAP) identification number and a PAPpassword for that ISP.

Different ISPs provide different services to users. Some ISPs (no or lowservice) may offer only a connection to the Internet without technicalhelp to a user connected to that ISP and further without any additionalfeatures. Other ISPs (full service) may offer many features such asencyclopedia type information, interactive games, access to otherwisecostly databases, etc.

A user in a commercial environment may operate a computer that isconnected to a LAN and also is connected to a modem. There are oftenbusiness considerations that require some communications with theInternet be accomplished through the LAN and other, especially personal,communications be accomplished through a modem. If a single softwareentity such as a browser is used for both types of Internet connection,several items of information need to be altered with the accompanyingchance for error and frustration of the user.

When a computer is subjected to stress such as by a large and suddenvariation in supply voltage (i.e. an electrical spike), there may becorruption of data in the software and/or data banks of the computer.When such corruption concerns the data needed to communicate with theInternet, a considerable amount of time is often required to ascertainthe cause of the failure to attain communication and further time isrequired to correct the problem.

Some Internet users are highly mobile and may need to access theInternet from various locations, some of which locations do not have alocal phone number for communicating with the normally used ISP. Such auser either must pay the cost of a long distance call or access adifferent ISP after modifying the appropriate data the operatingsystem's networking, dial-up-networking, or communications propertiesused to accomplish such access. Such modification always invites achance for erroneous data entry in the process and the accompanying timerequired to rectify the situation.

Another problem related to network use is related to electronic mailwhich terminology is popularly shortened to email. Email is used toquickly communicate with other users of connected network terminals. Theprocess is normally accomplished by sending a set of data including aheader portion, a message body and sometimes one or more fileattachments. Typically, the header contains the name of the recipient ina TO line, the sender in a FROM line and a subject in a SUBJECT line.Even if the message body and the attachments are scrambled or otherwiseencrypted a persistent entity monitoring the email being sent to andfrom a given terminal may glean considerable information from thesubject matter listed and from the number of messages sent between sameparties. This information is typically sent in clear text (unencoded) tofacilitate the delivery of email to the proper temporary storagefacility, normally a post office box like repository of the serviceprovider of the recipient, until such time as the recipient retrievesthe email from the service provider. The recipient also uses the headerinformation in determining priority of messages to be read.

A further problem is third party mail relay. This is a process wherebyjunk emailers use a service system other than their own to send massiveamounts of mail without paying for the service. The massive amount ofmail can so overload the system that an invaded system can crash,overload or otherwise be damaged. This overload is termed in the art asa denial of service attack. The overall process of sending massiveamount of junk email is termed “spamming”. The third party mail relayprocess is also used to bypass other systems filters which are set up toblock mail from the junk emailers system.

In view of the above, there exists a need to quickly and easily accessthe Internet from various locations, being able to access ISPs providingdifferent types of services, using various adaptors (ie modem or LANcard) and being able to choose whether preference should be given toitems such as cost and quality of service, without the user having to beconcerned about correctly modifying associated data and parameters suchas phone numbers, IDs, passwords etc used by the Internet software.

There is a further need to be able to send email to others in a mannerwhich minimizes the possibility that unauthorized entities may be ableto retrieve significant data from email header information.

Also there is a need to prevent junk emailers or other unauthorizedparties from using the third party mail relay process in connection witha network service system.

DESCRIPTION OF THE INVENTION

The entire contents of Provisional Patent Application Serial No.60/050,186, entitled: “Multi-User Internet Dispatch System,” filed onJun. 19, 1997, including appendices, are incorporated herein byreference for all purposes.

It should be noted that the present invention applies to any network orinterconnected set of networks. However, since the Internet is a wellknown example of an interconnected set of networks, Internet terminologyand interaction examples will be used in the explanation of thisinvention.

The present invention solves all or some of at least ten problems:

-   1 Eliminates the need for a computer user to configure and    reconfigure computer networking software for network access through    a multiplicity of ISPs and Network Access Providers (NAP) (companies    which own the telephone networks and modem banks such as AT&T, GTE,    UUNet, PSI, etc.).-   2 Allows a Network Re-seller such as an Internet Service Provider to    offer network access via a multiplicity of Network Access Providers    based on cost, location, availability, reliability, etc.-   3 Allows a Network Re-seller to balance network loads through a    multiplicity of Network Access Providers and across a multiplicity    of network computer servers.-   4 Eliminates the need for a computer user to know or configure    network access telephone numbers or network access protocol    identification numbers.-   5 Eliminates the need for a computer user or mobile computer user to    reconfigure remote network access software to connect to a network    from a remote location.-   6 Allows multiple users to use a single computer each with their own    unique networking attributes and unique network identity.-   7 Allows separate and distinct identifications (ID) and passwords    for different services and network functions such as PAP IDs and PAP    password, Email ID and password, etc.-   8 Provides a user with true network anonymity by assigning    independent non-user specific identifications and passwords for such    things as PAP authentication, FTP and Email logins, News Server    logins, and network server logins.-   9 Provides Email anonymity by transmitting and receiving all email    through a third party (broker) wherein, if appropriate, aliases may    be used for all un-encrypted data and these aliases may be changed    periodically by the system in a manner transparent to the user.-   10 Eliminates third party email relay (SPAMMING) by transparently    authenticating each user-system prior to giving access to a sendmail    server.

This invention relates to network connections, such as the Internet, andallows systems to be independently, transparently and dynamicallyconnected or reconnected to a network based upon any number ofattributes such as user or group identity, cost, availability,reliability, etc. Further this invention supports many types of physicalconnections such as telephone dial-up connections, ISDN connections,Ethernet, and other local area networking connections. It should benoted that while Internet terms such as ISP are used throughout thisdescription, the invention is operable with any network or portion ofany network and thus terms such as NSP (Network Service Provider) havebeen coined for use in the claims to identify similar or analogoussystems and devices.

A traditional network connection requires someone skilled in the art ofcomputer networking to setup and configure both network related hardware(such as modems or Local Area Network cards (Ethernet, Token-ring orother cards) and network software. The invention eliminates the need forsuch network configuration skills.

The invention configures and reconfigures network related software tosupport multiple users with multiple network protocols and/or multiplenetworks using the same protocol without the need of any computernetwork configuration skills and further allows the configuration to bechanged or modified dynamically without any user intervention.

The principles of the present invention and their advantages are bestunderstood by referring to the illustrated embodiment depicted in FIGS.1-21 of the drawings, in which like numbers designate like parts.

The invention includes software which is sometimes referred to asmiddle-ware because it resides between an electronic device operatingsystem and the end-users interface. The inventive software has all theattributes of middle-ware as it configures and manages networkcommunication equipment such as modems and Ethernet cards, networkprotocols such as the Transmission Control Protocol/Internet Protocol(TCP/IP), and the associated interfaces between the communicationequipment, network protocol and the computer's operating system for eachindividual user or groups of users.

Now referring to FIG. 1, there is illustrated a plurality of Internetservice providers (ISP1 through ISPx) 102 a, 102 b connected to anetwork 100 (sometimes referred to as the Internet). As will beappreciated, an Internet service provider (ISP) provides access for oneor more users 110 a, 110 b to the Internet 100 through a physicalinterface. The term “internet service provider” includes network accessproviders (NAPs) and Network Service Providers (NSPs) as well. Ingeneral terms, a user 110 connects to the ISP 102 via a communicationslink and the ISP 102 provides connection to the Internet 100. As will beappreciated by many users of the Internet, the ISP typically has manymodems accessible from a limited number of telephone numbers. Each ofthese modems has an assigned internet protocol (IP) address and normallyan assigned DNS name. Such assigned names and (IP) addresses will looksomething like “1cust239.tnt.orl1.da.uu.net” and [208.250.77.239]respectively. When a user contacts the ISP, the user is connected to thenext available modem and the IP address of that modem becomes the IPaddress of that user for the remainder of that connection session. Theuser 110 may include a single computer, group of computers, local areanetwork, or a larger network connected to the ISP 102 via acommunications link. However, in most applications, the user 110 willinclude a single user requesting access time to the Internet 100.

The present invention provides a means for transmitting ISP-specificaccess information to a user 110 via a communications link (preferably,the Internet 100) that allows the user 110 to gain access to theInternet 100 through a selected one of the plurality of ISPs 102.

To begin the process of the present invention, the user 110 installs(downloads) a client dispatch application program 200 (see FIG. 2) thatfurnishes the user 110 with one or more ISP access telephone numbers,one or more valid test and Registration Password Authentication Protocol(PAP) identification (ID) numbers, and a valid PAP password associatedwith a predetermined one of the ISPs 102. The client dispatchapplication 200 will be described in more detail further below. Theaccess information allows the user 110 to authenticate the user's rightto connect to the Internet via the predetermined ISP 102. The accessinformation mentioned comprises the previously mentioned accesstelephone number, the PAP ID, the PAP password and additionalISP-specific information required by the user 110 to gain access to theInternet 100 via the predetermined ISP 102 (collectively, ISP-specificconfiguration information) is initially provided by the client dispatchapplication 200. In addition, the client dispatch application 200provides basic configuration and initialization information(installation and configuration) to the user's computer to configure andmanage the network communication equipment, network protocols and theassociated interfaces needed to develop the capability to access theInternet 100, regardless of the particular ISP.

After the client dispatch application 200 is installed and the initialISP-specific information is known, the client dispatch application 200causes the user 110 to automatically transmit access information to thepredetermined ISP 102 (ISP1 102 a or ISPX 102 b). The line ofcommunication through which the access information is transmitted to thepredetermined ISP 102 by the user 110 (USER1 110 a or USERX 110 b) isidentified by the reference numerals 111 a, 111 b, 115 a, 115 b,depending on the particular user (USER1 110 a or USERX 110 b) and theparticular ISP (ISP1 102 a or ISPX 102 b). Upon receipt of the accessinformation, the ISP “authenticates” the user 110. The ISP 102 checks tosee whether the PAP ID and PAP password received from the user is valid.It will be understood that the authentication process performed by theISP 102 utilizes one or more appropriate methods (such as RemoteAuthentication Dial-In User Service (RADIUS)) which are normallyassociated with an authentication server running a database at the ISP,Network Service Provider (NSP) or the NAP. If the PAP ID and/or PAPpassword are not valid, the ISP 102 will disconnect the user or notifythe user that the PAP ID and/or PAP password is invalid. If valid, theuser 110 and the ISP 102 create a point-to-point protocol (PPP) (i.e.,communications connection) which is identified in FIG. 1 by referencenumerals 112 a, 112 b, 116 a, 116 b, depending on the particular user(USER1 110 a or USERX 110 b) and the particular ISP (ISP1 102 a or ISPX102 b). The PPP allows the ISP 102 to transmit/receive informationto/from the user 110. As a result, the user 110 is given access to theInternet 100 and the ISP generates an internet protocol (IP) address touniquely identify the user on the Internet 100. The particular IPaddress assigned to the user 110 depends on the IP addresses that areavailable and assigned to the particular ISP 102 to which the user 110is connected. An IP address is presently 32 bits and is normallyrepresented with four decimal numbers each ranging from 0 to 255 (e.g.128.54.28.200) where each decimal number represents one byte of the 32bits.

In accordance with the present invention, an Internet service provideraccess service or ASP (Access Service Provider) 106 is connected to theInternet 100. The external location, or physical address of the accessservice 106 is defined by a predetermined and unique address (i.e., IPaddress). After the user 110 gains access to the Internet 100 via one ofthe ISPs 102, the client dispatch application 200 resident in the user'scomputer transmits a data message to the access service 106 through theInternet 100 using the predetermined address of the access service 106.This data message is sent via a path identified as TCP/IP 120 or TCP/IP122, depending on the particular ISP 102 to which the user 110 isconnected for access to the Internet 100. The communications linkprotocol used for Internet 100 communications is defined as TransmissionControl Protocol/Internet Protocol (TCP/IP) and is well known in theart. As will be appreciated, other network communications protocols andstandards may be used during the present or in the future by the presentsystem invention due to the flexibility provided in the use of multipledatabases to store various types of data. The data message transmittedfrom the user 10 and received by the access service 106 containsinformation about the user, including the user's identification andaddress, current PAP ID, time stamp information, and version informationof the client dispatch application 200 operating on the user's computer,etc. In response to the user information received, the access service106 transmits an access information data message that includes accessinformation for a particular ISP 102. The access information is specificto a dial-in telephone number of a particular ISP 102 and, upon receiptby the user 110, allows the user to gain access to the Internet 100 viathat particular ISP 102. The ISP-specific access information includes anISP phone number (for dial-in to the ISP), a PAP ID for the ISP 102, anda PAP password for the ISP 102, and may also include default routinginformation (i.e., gateway address information), default directoryinformation (including domain name server information), sub-protocolsfor the PPP for the ISP 102, and configuration information for thehardware (i.e. modem) of the ISP 102 (to configure the user's modem),such as data compression information and speed. The ISP-specificinformation may also include service option defaults such as Email IDs,POP protocols and browser information. The PAP ID may or may not be sentdepending on the current PAP ID information transmitted from the user110 to the access service in the data message (e.g., if the current PAPID and the new PAP ID are the same, a new PAP ID does not need to besent).

After receiving the ISP-specific access information, the client dispatchapplication 200 may disconnect the user 110 from the current ISP 102 andautomatically dial and reconnect the user 110 to the desired ISP 102associated with the ISP-specific access information. As will beappreciated, the desired ISP 102 may be another ISP or may be the sameISP to which the user was previously connected, depending on theattributes of the particular ISP desired to be used for access to theInternet 100. If the ISP phone number (for dial-in to the ISP) and a PAPID received with the new access information, refer to the same ISP, theclient dispatch application 200 will not disconnect the user 100 and theuser's session will continue uninterrupted.

The access information data message includes the information necessary(PAP ID, PAP password, and other information if needed) to access adesired ISP 102 and, may include information for a plurality of desiredISPs 102, or multiple PAP IDs and PAP passwords for a desired singleISP. It will be understood that more than one access information datamessage packet may be utilized and transmitted, each packet containing aportion of the information packet or each may contain access informationfor a specific ISP 102.

The access service 106 offers Internet 100 access to the user 110 via aplurality of ISPs 102 based on cost, location, availability,reliability, etc. Based on the geographic location of the user, theaccess service 106 identifies, to the user 110, one or more ISPs 102that provide local access availability (via local telephone numbers ortoll free numbers) and provide the user 110 with information needed toaccess one of the identified ISPs (using the ISP-specific accessinformation). For desired low cost operation, the access service 106identifies the ISP 102 that provides the lowest cost access servicethrough which the user 110 may access the Internet 100 from theidentified ISP 102 at the user's location. For the reliabilityoperation, the access service 106 identifies one or more ISPs 102 thatprovide the highest reliability of connecting through which the user 110may access the Internet 100 from the identified ISPs 102 at the user'slocation. For the availability operation, the access service 106periodically receives availability information from each of theplurality of ISPs 102. In response to this information, the accessservice 106 identifies one or more ISPs 102 that provide the highestavailability through which the user 110 may access the Internet 100 fromthe identified ISPs 102.

As will be appreciated, the location operation, reliability operation,and availability operation may each provide to the user 110 the identityof multiple ISPs 102 or multiple dial-in numbers for a particular ISP102 whereby the user 110 will attempt connection in order of priority.For example, the user 110 may attempt access to a first ISP 102contained in a list of multiple ISPs 102 that have been identified basedon availability or reliability. If a connection is not successful withthe first ISP 102, the user 110 will next try a second ISP 102 in thelist, and so on, until a connection made. In another mode of operationexample, the user 110 may attempt access to a first ISP 102 utilizing afirst dial-in number contained in a list of multiple dial-in numbers forthe first ISP 102 that have been identified based on availability orreliability. If a connection is not successful with the first dial-innumber, the user 110 will next try a second dial-in number in the list,and so on, until a connection is made. Further a combination of multipleISPs 102 and multiple dial-in numbers may be used.

Now referring to FIG. 2, there is illustrated a block diagram of theaccess service 106 connected to the Internet 100 and a block diagram ofthe user 110 connected to the Internet 100 via the ISP 102. The user 110may be a computer system that includes the client dispatch application200 and the computer's operating system 202, as well as a registry orinitialization file(s) 212, a physical adaptor file(s) 214, and aprotocol file(s) 216. The files 212, 214, 216 are operating system files(system configuration files) that provide the user 110 with systemconfiguration information for supplying the basic capabilities needed tosuccessfully connect the user 110 to a network, such as the Internet100. The client dispatch application 200 correctly configures and setsthe system configuration files 212, 214, 216 with the necessary systemconfiguration information, including network protocols, adapterinformation, IP addresses, domain name system (DNS) server addresses,gateway addresses, other operating system binding functions, dynamichost control protocol options, and any other system options. As will beappreciated, the system configuration information necessary for the user110 to access the Internet 100 is well known in the art.

The user 110 also includes several databases for storing information,including a phone database 204, a network services database 206, abutton bar database 208, and a user database 210. As will beappreciated, the databases 204, 206, 208, 210 may be combined into asingle database, may be separate, and/or may be relational. Generally,the client dispatch application 200 includes the databases, or generatesthe databases and stores pre-loaded information into the databases uponinstallation of the client dispatch application 200 on the user 110computer.

The phone database 204 includes one or more dial-up telephone numbersfor the access location(s) of each of the ISPs 102. Each dial-up numberentry includes associated information including on-off field data, state(or a toll free number), city, dial-up telephone number, type of modemssupported (analog or digital), whether the number is available forregistration, identity of the ISP that owns the dial-in number (ID forprovider), sequence number (order for putting number in a specificarea). Some of the foregoing data is access information. An example ofsome of the contents of the phone database 204 and its data entries isset forth in Appendix A which is hereby incorporated by reference.

The network services database 206 includes access information for eachdial-in number contained within the phone database 204. Each of thestored dial-in numbers is associated with an ISP 102. The accessinformation for each dial-in number (for a particular ISP) includes oneor more PAP IDs, one or more PAP passwords, default routing information(i.e., gateway address information), default directory information(including domain name server information), sub-protocols for the PPP,and configuration information for the hardware (i.e. modem of the ISP)to configure the user's modem, such as data compression information andspeed. The network services database 206 may also include service optiondefaults such as Email IDs and the POP protocols and browser informationassociated with the dial-in number. The network services database 206also includes the basic configuration and initialization informationnecessary to configure and manage the network communications equipment,network protocols and associated interfaces for the user 110 for basiccommunications between the user 110 and the Internet 100. In addition,the network services database 206 includes information relating to thetype of service (type of account) requested by the user 110, such as the“lowest cost service”, the “highest reliability service”, the “mostreliable service”, or combinations thereof, plan pricing anddescriptions, and includes information identifying one or more primaryprocesses to be performed by the client dispatch application 200. Aswill be appreciated, some of the information in the network servicesdatabase 206 and the phone database 208 may overlap. An example of thenetwork services database 206 and its data entries is set forth inAppendix A which is hereby incorporated by reference.

The button bar database 208 includes information related to button barcreation and modification. All functions may be initiated through thehuman interface—a Toolbar (also described in the art as a button bar andbasic examples of which may be found in many present day computerapplications). The Toolbar of the present invention has some uniqueproperties as it can be dynamically changed or updated via a Pingerprocess or a MOT script. As defined in this application and as will bedescribed in more detail later, a Pinger process comprises an entitythat acts transparently as a “services” coordinator to provide and/oradminister the following:

-   -   1. Heartbeat service to help maintain network connectivity with        a client.    -   2. Authentication services that securely authenticate client        access to email, commerce, and other public and private network        servers and services.    -   3. Update services that can perform client software, database,        and maintenance services during periods of inactivity.

The Pinger entity, as suggested above, has, as one of its functions, theresponsibility of providing database updates to the client user. When aMOT script is used, it can be part of an E-mail message, an HTTP webdocument download and so forth, which transparently automates theToolbar update. The Toolbar can be integrated with ticker tape which canspawn MOT scripts, URLs, or execute programs. Each Toolbar button may beprogrammed with a function in the button bar database 210. The Toolbarreads a plurality, for this example five, of attributes from the buttonbar database 210:

-   -   1. Caption—Title or Button Name.    -   2. Enabled—Enables or disables the button function    -   3. Execution Type—This attribute supports the following types        and further determines if the fifth attribute read by the        toolbar would be “Execute File” (5a) or “URL” (5b)        -   DDE to a URL        -   DDE to a URL without going online        -   Launch a Program or Script        -   Launch a Program or Script and wait to complete before            continuing        -   Go online and then launch a program or Script        -   Change Preferences        -   Change Passwords        -   Display Account Information        -   Set Dialing Properties        -   Execute a MOT script        -   Jump to another Tab or Button on the Toolbar        -   Reload the Toolbar's Tabs and/or Buttons    -   4. Hint—Button functionality description    -   5a. Execute File—Command line of file to be executed    -   5b. URL—URL for a browser to open whether remote or local        -   When a user clicks on one of the Toolbar functions or the            Ticker tape, the appropriate procedure is started. For            example, if a button is programmed to go to the USA Today            (button Caption) web site the Execution type would be set to            “DDE to a URL” and the “URL” would be set to something            similar to http://www.usatoday.com/ and the “Hint” would be            set to something similar to “Open to XXXXXXXXX Web site for            the latest news!”.

As will be appreciated, a MOT script defines how to build a button barusing the button bar database 210 and its database entries. The MOTscript is typically associated with a Web page and when the user 110clicks on the Web page, the MOT script associated with the Web page isread back by the client dispatch application 200. The client dispatchapplication 200 uses the particular MOT script and the button bardatabase 210 information and builds the button bar automaticallyaccording to the MOT script specifications. An example of the button bardatabase 208 and its data entries is set forth in Appendix A which ishereby incorporated by reference.

The user database 210 includes information related to the user 110, suchas name, address, phone numbers, billing information, Email ID and Emailpassword, type of account, and unique PAP ID and PAP password, ifapplicable. It will be understood that the user database 210 may bemerged into the network services database 206. An example of the userdatabase 210 and its data entries is set forth in Appendix A which ishereby incorporated by reference.

The access service 106 is connected to the Internet 100 and is definedby a predetermined and unique address (i.e., IP address). The accessservice 106 includes one or more network servers/databases 220. It willbe understood that access service 106 includes a computer system havingone or more processors, memory, and support hardware (all not shown inthis figure) for processing and storing information and datacommunications. The network/databases 220 store information relating tothe user(s) 110, including the same information that is (or wouldnormally be) in the user database 208, and also includes session keys(transaction keys) billing data, connection history data, ISP-specificaccess information, and information about what procedures a user 110 hasperformed, and the like. Specific functions of the access service 106have been described in the foregoing and will be described in moredetail below. The Pinger entity may be a part of the access serviceprovider 106 or it may be separate. For the present discussion, it willbe assumed to be part of the access service provider 106.

After the user 110 connects to the Internet 100 via a predetermined ISP102, the client dispatch application 200 dispatches an initial “pinger”message to the access service 106 via the Internet 100. Included withinthe pinger message is header information that includes the current userID, account owner ID, PAP ID, the current IP address assigned to theuser 110, Group ID, the users system's current time, database (204, 206,208, 210) revisions levels, client dispatch application 200 and otherrelated software revision levels.

All communications between the client dispatch application 200 and theaccess service 106 take place through a process identified as thePinger. The Pinger provides secure and unsecure periodic bidirectionalcommunication between the user 110 and the access service 106. Thefunctions of the Pinger are as follows:

-   -   Read, Write or Update any entry in any of the databases 204,        206, 208, 210 of the user 110 and any of the databases 220 of        the access service 106 and further initiate a secondary        transmission when appropriate.    -   Execute a program or script with command line entries if        appropriate.    -   Save a file or script and further initiate the execution of the        file or script when appropriate.    -   Continue Transaction.

With these functions, the client dispatch application 200 can requestdatabase updates or save files for execution later, and the accessservice 106 can initiate events, database updates, or save files forexecution later. The Pinger process also provides a “heartbeat”mechanism to prevent the premature disconnection of the user 110 fromthe network by an ISP 102. That is, many ISPs 102 have a modeminactivity timeout interval that disconnects users after some shortinterval of time if there has been no network activity during thatinterval of time. The heartbeat function is programmable and, in thepreferred embodiment, is set at five minutes during the user's firstthree hours of connection time and increases by five minutes each halfhour thereafter. In the heartbeat function, the client dispatchapplication 200 transmits the user's ID to the access service 106.

The pinger is initiated by the client dispatch application 200 uponconnection to the network 100. The client dispatch application 200transmits header information to the access server 106 using the IPaddress of the access server 106. The header information includes thecurrent user ID, account owner ID, PAP ID, the current IP addressassigned to the user 110, Group ID, the users system's current time,database (204, 206, 208, 210) revisions levels, and client dispatchapplication 200 and other related software revision levels. With thisinformation, the access server 106 determines whether a user 110 ismaking two connections while only paying for one and thus needs to bedisconnected, or is a user 110 that needs a database or file update. TheContinue Transaction function provides a mechanism to partially transmitdata and commands over multiple sessions (successive connections by theuser 110 to the network 100) without having to restart the transactionfrom the beginning.

While the pinger process (transparent to the user) allows the clientdispatch application 200 and the access service 106 to interact anddownload database updates (or other information) to the user 110, thereis an alternative way to provide the updates to the databases, etc. atthe request of the user 110. The access service 106 may provide a Webpage whereby when the user 110 clicks on the Web page, a MOT script andother data associated with the Web page is transmitted from the Web pagesite to the client dispatch application 106. This gives the user 110 thecapability to request a data update (or to receive other information).Alternatively a MOT script and other data can be transmitted via anemail message, an FTP (file transfer procedure) site or other similarnetworking storage and transport mechanism to the client dispatchapplication.

The Script Language used by the Pinger and elsewhere in this applicationfor patent is designated by the term MOT (see FIG. 8). MOT is not,however, an acronym for anything meaningful. The script language is aninterpretive language which is stored in an encrypted file from whichthe interpreter reads to initiate the MOT client dispatch application.The MOT client dispatch application can read and write database (db)entries, Operating System initialization file entries (INI and RegistryFiles), and ASCII Text files. Further, the MOT client dispatchapplication can spawn executable programs, network connection, AWKscripts, and other MOT scripts.

Now referring to FIGS. 3 through 7, there is illustrated the process ofthe client dispatch application 200. The flow diagrams of FIGS. 3-7 arerepresentations of closed-loop programming (structured programming). Theclient dispatch application 200 performs five primary procedures orfunctions as set forth in the CASE block. These include theinstallation, registration, regular use, manual update, and multi-dialprocedures. Within the multi-dial procedure are several sub-functionsdefined as the low cost, reliability, location, availability,busy-sequence, and single dial/multi-login sub-functions shown andexplained subsequently in connection with FIG. 7. The client dispatchapplication 200 manages the procedures based upon data from one or moredatabases of the access service 106 or other inputs received from theaccess service 106, the user's databases 204, 206, 208, 210, and/or theuser's computer operating system files. It will be understood thatdatabases and database information may be encrypted to prevent a userfrom tampering with entries contained therein.

Now referring to FIG. 3, there is illustrated a flow diagram of aninstallation procedure 300 of the client dispatch application 200. Theprocedure 300 starts by reading information from the network servicesdatabase 206. The network services database 206 forms part of thesoftware package which is loaded into a network access device, such asthe user 110 (computer). The network services database 206 includesbasic configuration and initialization information necessary toconfigure and manage the network communication equipment, networkprotocols and the associated interfaces between the communicationequipment and network protocols and the computer's operating system.

After the network services database 204 is read, the user's operatingsystem files (which in the case of a Windows operating system comprisesRegistry and INI files, Protocol files, and Physical Adapter files) areexamined to determine if any networking options have been installed andwhether or not the files, if installed, are correct and configuredproperly as part of the “No Protocol” decision block. If no Protocol orAdapter has been installed, the “True” path will be followed whereby theInstallation function will configure the Adapter and necessary Protocolto successfully connect the user 100 to a network such as the Internet100. If the Protocol or Adapter that is installed is misconfigured, the“False” path will be used whereby the Installation function willreconfigure the Adapter and necessary Protocol to successfully connectthe user 100 to a network such as the Internet 100. As part of theconfiguration process, it may be noted that the correct configurationfor utilization of the TCP/IP Protocol would include configuring andsetting the proper Operating System Registry and INI (initialization)files with the necessary Protocol configuration information in instanceswhere the operating system is a version of windows. Such informationincludes: IP addresses whether statically or dynamically assigned,Domain Name System (DNS) name server addresses whether statically ordynamically assigned, Gateway Addresses whether statically ordynamically assigned, Other operating system Binding functions, DynamicHost Control Protocol options, Windows Internet Naming Service (WINS)options whether statically or dynamically assigned, and the assignmentof such Protocol functions to be utilized by the appropriate Adapter.The function of configuring or reconfiguring is executed near thebeginning of each of the five primary procedural (300, 400, 500, 600,700) tasks of the client dispatch application 200 to ensure successfuloperation of a network connection even for those instances where acomputer user accidentally misconfigures their system and thereby makesnetworking inoperable.

After the successful configuration of both the Adapter and the Protocol,the procedure 300 proceeds to the “Which Adapter” decision block. Theappropriate adapter is utilized which is either the adapterpre-programmed into the network services database 206 (if available) orif there is only one Adapter then it will be used. If the Adapter is aModem, the “Modem” path will be followed to read from the networkservices database 204 to determine if the user 110 chooses a dial-inlocation under the case of “User Look-up” or if the modem shall beprogrammed to dial a “Pre-Defined” dial-in phone number reference in thenetwork services database 204 and stored in the phone database 204. If adatabase entry in the network services database 206 is set to allow theuser 110 to choose a dial-in location, then the user 110 chooses alocation based on Country, State or Province, and City in accordancewith the “User Picks Dial-In Location” block. After the user 110 selectsthe proper dial-in location, the installation procedure 300 reads fromthe phone database 204 to determine the dial-in phone number to use. Ifa given location has multiple dial-in phone numbers, a dial-in number isselected based upon attributes read from the network services database206 (and/or the phone database 204). Such attributes includeinstallation dial-in numbers (dial-in phone numbers which are onlyavailable during installation or testing). Although not pertinent to theinstallation procedure 300, other attributes of phone numbers appearingin the phone database 204 include Registration Dial-in Numbers (phonenumbers and locations which appear to a user during registration),Sequence Numbers (a prioritized list of phone numbers which shall betried in sequential order to produce the highest probability ofconnection), Available ISP numbers (phone numbers of a given ISP'smodems), Currently Valid Numbers (phone numbers which are currentlyvalid for use by a given users), or any combination of theaforementioned.

If a value in the network services database 206 is set for the user 110to use a predefined dial-in number (such as an 800 type toll-freenumber) the client dispatch application 200 will read the appropriatepredefined phone number entry from the phone database 204. After theclient dispatch application 200 has determined the proper dial-in phonenumber, whether user selected or pre-defined, the user's modem isinitialized and dialing occurs, as set forth in the “Dial & Connect”block. If the modem is busy, it will either continue to retry the samephone number or initiate a multi-dial procedure 700 (as set forth inFIG. 7) depending on the outcome of the “Multi-dial Mode?” decisionblock (from an entry in the network database services 206). If the“False (Retry)” path is followed, the same number is dialed until theuser 110 “gives up”. If a Multi-Dial mode “True” path is followed, basedupon the entry in the network services database 204, the multi-dialprocedure 700 is initiated and other dial-in numbers will be tried togain access to the network. The multi-dial procedure 700 is one of thefive primary procedures of the client dispatch application 200 and isexplained in more detail in connection with FIG. 7.

Once a connection is made, the “False” path from the “Busy?” decisionblock is followed and communication with the access service 106 beginsby sending an installation PAP ID and PAP password (read from thenetwork services database 206) to the access service 106 for transparentlogin authentication as shown by the “Get Information From Server”block. Once the login has occurred, communication with the accessservice 106 is established, and transfer of data begins. The datatransferred during the installation procedure 300 may contain some basicsystem information about the user's computer system, the type ofconnection being used and the location from which the connection hasoccurred. Once this information is received at the access service 106,the access service 106 sends appropriate information back to the clientdispatch application 200. Such information may include updates to thephone database 204 including “Location” addition or subtractions, phonenumber changes, and updates to the network services database 206including ISP additions and subtractions, group, user, or multiple userspecific configuration, DNS and IP information, etc. Updates to thedatabases 204, 206, 208, 210 which reside on the user's computer canoccur transparently to the user 110 whenever the user 110 is connectedto the Internet 100; thereby ensuring that the user's network relatedinformation is always current and accurate. Any updates received fromthe access service 106 are written to the appropriate database (i.e.network services database 206, phone database 204, or others) by theclient dispatch application 200. The client dispatch application 200also updates the network services database 206 to reflect “installationcomplete”. Thus, the client dispatch application 200 is informed thatthe next execution “Case” to start is “Registration” as will be shown inFIG. 4.

At this point, the dial-in location attributes (Installation dial-innumbers, Registration Dial-in Numbers, Sequence Numbers, Available ISPnumbers, Currently Valid Numbers) provide control mechanisms to ensurethat a user 110 receives the appropriate level of service for which theyare subscribed such as “the lowest cost service”, “the highestreliability service”, “the most available service”, or combinationsthereof. Further, these updated and database stored attributes allow forremote testing of the network communications (full connection TCP/IPtest to the Internet 100), the user's system for basic configuration,database integrity, network load balancing and the reduction of fraud bydynamic control of phone number validity.

If the Adapter used to connect to the network is a Local Area Networkdevice such as an Ethernet card, the “LAN” path is followed from the“Which Adapter” decision block. In this situation, once communicationwith the access service 106 is established, transfer of data and updatesbegin as described in the paragraphs above.

Now referring to FIG. 4, there is illustrated a flow diagram of theregistration procedure 400 of the client dispatch application 200. Theprocedure 400, as all primary procedures, starts by reading the networkservices database 204 to determine the appropriate execution “Case”, andin this case, the registration procedure 400. The registration procedure400 starts by reading the network services database 206 to gather thenecessary information, such as which Adaptor and Protocol to use andproceeds to configure and initialize the appropriate networkingfunctions to start the user registration process. A “Which Adapter”decision block includes the two paths of “Modem” and “LAN”. After adetermination is made as to which Adapter and Protocol to use, theprocess proceeds to the “(Re)Configure Adapter Protocol” block toconfigure and initialize the appropriate networking functions to startthe user registration procedure 400 (i.e. configuration process for theuser's computer).

The registration procedure 400 comprises several forms (pop-up forms)into which the user 110 enters specific information about the user 110.Such information typically will include Name, Address, Phone Numbers,Credit Card and/or Banking Information, Referral Information (ifavailable), Personal Security information (like: mother's maiden name),Birthdate, and Preferred E-mail Identity and Preferred E-mail DomainChoice. The registration information for each user 110 is stored in thenetwork services database 106 and/or a user specific database 210, aswell as information about the user's system and revision levels of theclient dispatch application 200 and databases (204, 206, 208, 210). Uponcompletion of the new user registration forms as indicated by the“Update DBs with New User Infornation” block, the client dispatchapplication 200 initiates communications with the access service 106 asdescribed earlier. The adapter used, as determined by the lower most“Which Adapter” decision block, will be the adapter determined and usedduring the installation process. Once communication with the accessservice 106 begins, the client dispatch application sends all theinformation that was added or updated into the network services database206 (or user database 210) of the user 110 to the access service 106 asindicated by the “Send Information To Server” block. The access server106 transmits the received information plus additional information, suchas one or more user assigned PAP IDs and PAP passwords, Email IDs andEmail Passwords, back to the client dispatch application 200 forcomparison and verification of the information that was sent asindicated by the “Get Information From Server” block. If the informationreturned is not identical to the information which was sent, the clientdispatch application will resend the information again to the accessservice 106 along the path commencing with the “Notify User ofError-Retry” block. This process will continue until all transmittedinformation from the client dispatch application 200 to the accessservice 106 matches all information returned to the client dispatchapplication 200 from the access service 106 or when a maximum retryvalue is reached in accordance with the “Quit?” decision block. In thepreferred embodiment, the maximum retry value is five. If the clientdispatch application 200 reaches a maximum retry value, an error messageis sent to the user 110 notifying the user that an Error has occurredand to try reconnecting or registering again. This error messagecomprises a part of the “True” path output of the “Quit?” decisionblock.

It will be understood that registration procedure 400 may be designed tohave an alternate process of prompting the user 110 to use an alternateAdapter or Protocol and then retry where such an alternate process maybe deemed appropriate.

If other users (sub-users) are permitted to access the network underthis initial user's authority, such as other family members, theregistration process for these other users can be started during aregular use procedure 500 described in connection with FIG. 5. Uponcompletion of a user's initial registration, the user's network accessdisplay device will display an Electronic Registration Number (ERN)which, with other personal security information, can be used later torefresh a system as described below.

The registration procedure 400 also allows users registered with theaccess service 106 to temporarily use a computer or other network accessdevice or permanently use a secondary network access device by using arefresh function which bypasses the standard registration form screensby asking the user if they have already registered. If the user haspreviously registered, the refresh process of the registration procedure400 will connect, communicate with the access service 106 and downloadall the user information sent during the user's initial registration andthe client dispatch application 200 will update the appropriatedatabases (204, 206, 208, 210) on the user's network access devicesstorage system.

Now referring to FIG. 5, there is illustrated a flow diagram of aregular use procedure 500 of the client dispatch application 200. Theregular use procedure 500 is enabled after a user 110 has both installedclient dispatch application 200 on a particular computer system or othernetwork access device and registered with the access service 106.

The regular use procedure 500 functions to connect a user 110 to thenetwork 100 using a login and password access which is transparent tothe user 110. This is accomplished by reading the network servicesdatabase 206 for login information such as the user PAP ID and PAPpassword as shown in the “Read NS.db” block. After reading the necessaryinformation from the network services database 206 and prior to the user110 logging onto the network 100, the user 110 is given an opportunityto change the user's dial-in Location if the user 110 is using a modemas an Adapter, as illustrated by the “Change Location” decision block.If the Adapter is a modem, and the user 110 desires to change locations,the user 110 is presented with a “chooses a location” form that may beidentical to one seen by the user 110 during registration. The “choosesa location” form allows the user 110 to select a local dial-in locationfrom pull down menu selections based on Country, State or Province, andCity selections for a given ISP 102 for which the user PAP ID and PAPpassword are valid. After the user 110 selects the proper dial-inlocation, the phone database 204 is read to determine what dial-in phonenumber to use.

If a given location has multiple dial-in phone numbers, a dial-in numberis selected based upon attributes that are read from the phone database,user db, network services database 206 or any combination thereof aspart of the “Dial & Connect” block. As discussed elsewhere, and inparticular in connection with FIG. 3, such attributes includeInstallation dial-in numbers (dial-in phone numbers which are onlyavailable during Installation or testing), Registration Dial-in Numbers(phone numbers and locations which appear to a user duringregistration), Sequence Numbers (a prioritized list of phone numberswhich shall be tried in sequential order to produce the highestprobability of connection), Available ISP numbers (phone numbers of agiven ISP's modems), Currently Valid Numbers (phone numbers which arecurrently valid for use by a given users), or any combination of theaforementioned.

After the user 110 establishes a connection to the access service 106, a“pinger” function is initiated as discussed previously. The pingerfunction causes the client dispatch application 200 to transmit headerinformation to the access service 106, as set forth in the “SendInformation To Server (Pinger)” block. The header information mayinclude a Unique Identification string for the user (user ID, PAP ID,etc.), a unique computer identification string (IP address, etc.), timestamp information, and revision information for the client dispatchapplication 200 and databases 204, 206, 208, 210, as described earlier.After receipt, the access service 106 reviews the header information todetermine what, if any, updates are required to be made to the userclient's dispatch application, databases, or network access devicesoperating system. Such updates may include: new dial-in locations, newidentification information such as PAP IDs, network authenticationpasswords such as PAP passwords, other IDs, other passwords, change ofphone numbers, change of area codes, low cost ISP, dial-in locationpriority sequence numbers, or any combination thereof, or any otherinformation relating to gaining access to the ISP 102. If any updatesare required, these are supplied by the access service 106 and anynecessary updates will take place transparent (automatic while the useris logged on) to the user 110 as part of the “True” process pathemanating from the “Transparent Update Required?” decision block. Ifsuch updates require user intervention, such as rebooting the user'scomputer, the user 110 will be notified prior to the update and/or priorto a reboot as part of the “Notify User to Restart” block. Updates whichrequire a lot of time, may span multiple log-ins (to the network 100) bythe user 110 with partial updates being performed until the fullcompletion of the update. The partial updates will take place when theusers system is connected but idle and/or during a “pinger/heartbeat”function.

Now referring to FIG. 6, there is illustrated a flow diagram of a manualupdate procedure 600 of the client dispatch application 200. The manualupdate procedure 600 provides a mechanism for a user 110 to manuallyrecover, change, modify or update the client dispatch application 200and the databases 204, 206, 208, 210. This capability is useful for ISPsmanaging customers with billing issues, as well as for servicingcustomers with special system configuration issues.

The manual update procedure 600 initiates and makes a network connectionusing a special set of log-in information defined herein as the “ManualUpdate PAP ID and PAP password” (the manual update PAP ID and PAPpassword, including the Installation, Multi-dial and Test PAP IDs andPAP passwords are incorporated into the user's installed client dispatchapplication 200 as part of the network services database 206 and are noteasily accessible to the user 110). If a connection is not immediatelyobtained, the adapter and protocol checking is completed as set forth inconnection with the previous Figure (and description thereof) and as setforth in this flow diagram, via the “False” path output of the“Connected?” decision block. Once the connection is established, eithervia the “LAN” path from the “Which Adapter” decision block or the“False” path from the “Busy?” decision block, the “pinger” function isinitiated as indicated by the “Send Pinger Information to Server” block.If there already is a connection, the “True” path is followed from the“Connected?” decision block.

Once communication is established by the client dispatch application 200with the access service 106, pinger header information, any specialdatabase update request, and the like, etc. is transmitted from theclient dispatch application 200 (generated from the network servicesdatabase 206 and/or the user database 210) to the access service 106, asshown by the “Send Update Request to Server”, in order to establish theidentity of the user 110 and system that is requesting an update ofinformation from the access service 106. The access service 106 usesthis update request information to generate any updated informationwhich is needed to update a specific user, group of users, a specificnetwork access device such as the computer, a group of computers, or anycombination thereof and sends any required information back to the user110 to update the appropriate databases 204, 206, 208, 210 or Registryor INI, Adapter, and/or Protocol files 212, 214, 216 (operating systemfiles). Upon completion of the update, the client dispatch application200 disconnects the user 110 from the network (breaks the networkconnection) and if appropriate, the user 110 will be notified that thenetwork access devices operating system must be rebooted in order forthe update to take effect.

Now referring to FIG. 7, there is illustrated a flow diagram of amulti-dial procedure 700 of the client dispatch application 200. Themulti-dial procedure 700 provides the access service 106 with amechanism to control access by a user 110, a group of users, a computer,a group of computers, a local area network (LAN) of computers, or anycombination thereof, to the Internet 100, based upon any one of thefollowing seven sub-function attributes: Cost, Availability,Reliability, Location, Busy-Sequence, Service Selected, or SingleDial/Multi-Login. The multi-dial procedure 700 is initiated by one ofthe other primary procedures 300, 400, 500, 600 (see FIGS. 3 through 6)of the client dispatch application and/or by a multi-dial procedure tagprogrammed into the network services database 206.

When the multi-dial procedure 700 is initiated in response to a busysignal received during operation of one of the other primary procedures300, 400, 500, 600 and the multi-dial procedure tag is enabled in thenetwork services database 206, the multi-dial procedure 700 initiates aBusy-Sequence sub-function. The Busy-Sequence sub-function initiates oneof the other multi-dial procedure sub-functions, re-dials the samedial-in number before initiating one of the other multi-dial proceduresub-functions, or dials a new dial-in number identified in the nextsequential “area” location from a list of area locations available, allin response to database information based on the user's selected plan.The list of “area locations available” is based on the type of serviceplan (also found in the network services database 206) subscribed to bythe user 110 and/or on PAP IDs and PAP passwords stored in the networkservices database 206. If the user 110 has chosen to subscribe to ahigher cost plan, multiple PAP IDs and PAP passwords for multiple ISPs102 may be stored in the network services database 206 (certainlocations may only have a single ISP). As a result, a list of availabledial-in locations may contain one or more dial-in numbers from one ormore ISPs 102. Alternatively, multiple ISPs 102 may have PAP ID and PAPpassword sharing agreements allowing a single user PAP ID and PAPpassword entry in the network services database 206 to generate adial-in location list from multiple ISPs 102. In any case, theBusy-Sequence sub-function sequentially attempts to make a connection toan ISP 102 at each location until either a successful connection is madeor the user 110 aborts the connection attempt.

When the multi-dial procedure 700 is initiated for any reason other thana busy signal, the client dispatch application 200 reconfigures orreinstalls the system configuration adaptor and protocol informationnecessary for network connection. Thereafter, based on data in networkservices database 206, it is determined whether or not to initiate aconnection attempt to the Internet 100 using a pre-defined dial-innumber or location. If a connection is desired using a predefineddial-in number or location, the multi-dial procedure 700 uses one offour types of possible PAP IDs and PAP passwords. These types aredefined as a “multi-dial PAP ID and PAP password”, a “group PAP ID andPAP password”, a “user PAP ID and PAP password”, and a “test PAP ID andPAP password.”

When both the “pre-defined dial-in number” entry and a “General Use”entry are enabled in the network services database 206, a general useconnection to the Internet 100 is established using either the “groupPAP ID and PAP password” or the “user PAP ID and PAP password.” When the“pre-defined dial-in number” entry is enabled and the “General Use”entry is disabled, then the multi-dial procedure 700 establishes aconnection to the Internet 100 using either the “multi-dial PAP ID andPAP password” or the “test PAP ID and PAP password”. In either case, theuser's dial adaptor (modem) is configured with the ISP-specific accessinformation associated with the predefined dial-in number. After properconfiguration, the client dispatch application 200 automatically dialsand attempts connection to the ISP 102. If the line is busy, it isdetermined whether an alternate dial-in number should be used. If analternate number is not to be used, the dial and connect is retried withthe previous dial-in number. If an alternate number is to be used, thealternate dial number is read from the phone database 204 and the user'sdial adaptor (modem) is configured with the ISP-specific accessinformation associated with the alternate dial-in number.

Upon successful connection, if the connection is not a “general use”connection, the Service Selected sub-function is initiated (a doubledial procedure). If the connection is a “general use” connection, theclient dispatch application 200 transmits pinger header information tothe access service 106. In response, the access service 106 transmitsinformation to the user 110 (client dispatch application 200). Themulti-dial procedure 700 determines from this received informationwhether a transparent update is needed (i.e., update information in thedatabase(s) without user intervention). If so, the client dispatchapplication 200 updates the database(s) and determines whether adisconnect is required. If not, the user 110 continues regular use untildisconnected by some other means. If so, the user 110 is notified andmay be given the option to choose to disconnect or may be forced todisconnect.

If after a connection is made and the user 110 has used a PAP ID and PAPpassword that is used by another in order to establish the user 110connection, then the access service 106 updates the user's database(s)(possibly with a new and valid PAP ID and PAP password) and the clientdispatch application 200 either disconnects the user 110 (and notifiesthe user 110 that the PAP ID is not valid) or allows the user 110 tostay connected (if the user 110 has received a new and valid PAP ID).This particular process also applies to the regular use procedure 500(see FIG. 5).

In the preferred embodiment, when a “pre-defined dial-in number” entryin the network services database 206 is disabled, then the multi-dialprocedure 700 executes one or more of the seven sub-functions inresponse to entries in the network services database 206.

The Service Selected sub-function reads pinger header information fromthe network services database 206 and the user database 210 and sendsthis information in a data message to the access service 106 (to thenetwork server/database 220). The access service 106 uses theinformation to generate database updates (including new PAP ID, etc.)which may or may not assign, reassign, or update ISPs, dial-inlocations, PAP IDs and PAP passwords, dial-in numbers, network routinginformation, Adapters, Protocol, or any other information stored in thedatabases 204, 206, 208, 210. Such database updates are then transmittedto the user 110 and the client dispatch application 200 to update theappropriate database 204, 206, 208, 210. After the database informationis updated, the user 100 is disconnected, and the Regular Use primaryprocedure is initiated using the updated information received from theaccess service 106.

The “Low Cost” sub-function obtains information from both the networkservices database 206 and the phone database 204 and determines whichISP 102 and what locations (dial-in phone numbers for local access) havethe lowest priced service for a given user's dial-in location. Thelowest cost sub-function next determines if the user's PAP ID and PAPpassword stored in network services database 206 are valid (compare thecurrent user's PAP ID and PAP password with the user's currentlyselected dial-in location) for the ISP 102 that provides the low costconnection point-of-presence at the user's location. If the user PAP IDand PAP password are valid, the network connection sequence will dialand connect as described in the regular use procedure 500. If the userPAP ID and PAP password are invalid then this sub-function will initiatethe manual update procedure 600 requesting from the access service 106 avalid user PAP ID and PAP password for the ISP's dial-in network at theuser selected location. Then, the network connection sequence will dialas described in the regular use procedure 500.

The “Reliability” sub-function obtains information from both the networkservices database 206 and the phone database 204 and determines whichISP 102 and what locations (dial-in phone numbers for local access) havethe highest reliability of connecting the user to the Internet 100. Thisdetermination is based upon prior data (reliability data) transmitted tothe client dispatch application 200 from the access service 106 that isused to update the user databases. This data transmission occurs duringa previous session when the user 110 is connected to the Internet 100.The reliability data is transferred by the access service 106 to theusers 110 who have a reliability entry enabled in their network servicesdatabase 206. The reliability sub-function next determines if the userPAP ID and PAP password stored in the NS.db are valid (compare thecurrent user's PAP ID and PAP password with the user's currentlyselected dial-in location) for the ISP that provides the highestreliability at the selected location. When the user PAP ID and PAPpassword are valid, the network connection sequence will dial andconnect as described in the regular use procedure 500. When the user PAPID and PAP password are invalid, then this sub-function will initiatethe manual update procedure 600, as described in connection with FIG. 6,requesting from the access service 106 a valid user PAP ID and PAPpassword for the ISP's dial-in network at the user selected location.Then, the network connection sequence will dial as described in theregular use procedure 500 of FIG. 5.

Reliability refers to the ability to reliably connect on a first orsecond attempt (availability) and the ability to stay connected for asubstantial period of time without disconnection, due mainly because ofline noise problems, faulty equipment, etc. (integrity). Availabilityinformation used to determine availability of various ISPs 102 (anddial-in numbers) may include at least three types of information. Thefirst type of information includes availability information that isreceived by the access service 106 from the ISPs 102 themselves(typically updated periodically). The second type of informationincludes information in a client histogram (client specific) that isgenerated by the client dispatch application 200 of the user 110. Overan extended time during which the user 110 makes more and moreconnections to the Internet 100 (via an ISP 102), the client dispatchapplication 200 keeps track of the times a connection is made on thefirst try, second try, etc. for each dial-in phone number (and/or ISP)used by the user 100. From this, a client-specific histogram isgenerated that contains information about the past history of the user'sconnections. The third type of information includes information in aserver histogram that is generated by the access service 106. The accessservice 106 tracks and stores information relating to all ISPs 102 anddial-in numbers regarding past history connections. See also, thedescription set forth below in the availability sub-functiondescription. As will be appreciated, the reliability sub-function mayuse any one of the types of availability information, or combinationthereof, for determining the dial-in number (or multiple numbers inpriority) that will provide the user 110 with a high reliabilityconnection.

With respect to the integrity information used to determine theintegrity of the various ISPs 102 (and dial-in numbers), there are atleast two types of information. The first type of information includesinformation received via technical support inquiries to the accessservice 106 by the users 110. If the access service 106 receives a call(or calls) from users 110 regarding faulty lines and/or prematuredisconnects, this information can be tabulated and stored fordetermining integrity. Since the access service 106 stores data relativewhat ISP(s) 102 (and dial-in number(s)) a particular user 110 has beenusing (through information in the access service 106 database gainedthrough the pinging or heartbeat process—described earlier), the accessservice 106 can determine which ISP(s) 102 (and/or dial-in number(s))have relatively high and/or low integrity. In response to thisinformation, the access service can update the user's databases withthis information. The second type of information includes informationautomatically gathered by the access service 106 that includes a historyof the number of users, how long each has been connected, and whatISP(s) 102 (and/or dial-in number(s)) to which each user has beenconnected (through information in the access service 106 database gainedthrough the pinging or heartbeat process described earlier). The accessservice 106 can transmit the integrity data to the user 110 for use bythe reliability sub-function of the client dispatch application 200. Aswill be appreciated, the reliability sub-function may use any one of thetypes of integrity information, or combination thereof, for determiningthe dial-in number (or multiple numbers in priority) that will providethe user 110 with a high reliability connection.

From a combination of the availability information and the integrityinformation, the reliability sub-function determines the dial-in number(or multiple numbers in priority) that will provide the user 110 withhigh reliability connection.

The “Location” sub-function obtains information from the phone database204 and determines all the dial-in phone numbers available to a user 110from a selected location. The location sub-function generates a list of“surrounding area” locations into which user 110 may dial. The user 110then selects a dial-in number from this list. The location sub-functionnext determines if the user PAP ID and PAP password stored in thenetwork services database 206 are valid (compare the current user's PAPID and PAP password with the user's currently selected dial-in location)for the ISP 102 in which the user's computer will dial into the selectedlocation. When the user PAP ID and PAP password are valid, the networkconnection sequence will dial and connect as described in the regularuse procedure 500. When the user PAP ID and PAP password are invalid,this sub-function will initiate the manual update procedure 600requesting from the access service 106 a valid user PAP ID and PAPpassword for the ISP's dial-in network at the user selected location.Then, a network connection sequence will dial as described in theregular use procedure 500 of FIG. 5.

The “Availability” sub-function generates a dial-in location (number)list based upon user PAP IDs and PAP passwords stored in the networkservices database 206 and the type of service plan (also found in thenetwork services database 206) to which a user 110 has subscribed. If auser 110 has chosen to subscribe to a higher cost plan, multiple PAP IDsand PAP passwords for multiple ISPs 102 may be stored in the networkservices database. Accordingly, the list of available dial-in locationsmay contain one or more (multiple) dial-in numbers from one or more(multiple) ISPs 102. Alternatively, multiple ISPs 102 may have PAP IDand PAP password sharing agreements allowing a single user PAP ID andPAP password entry in the network services database 206 to generate adial-in location list from multiple ISPs 102.

As will be appreciated, the availability sub-function utilizes the sametype of availability information as described above in the reliabilitysub-function.

The availability sub-function utilizes one or more methods or theservice selected sub-function to increase the probability that the user110 at a given location will successfully connect on the first try. Thisfunctionality is based upon historical data (Histogram data) or realtime data supplied by an ISP to the access service 106. The historicaldata may include two types of data—Client Histogram data or ServerHistogram data. To accomplish the availability function, the ServerHistogram data, Client Histogram data, or the service Selectedsub-function is utilized, or any combination thereof is utilized, asdesired.

The Client Histogram data is based upon connection history of the user110. The Client Histogram data is not as beneficial, as other data,until a particular user 110 has consistently established a networkconnection (to the Internet 100) for a period of time sufficient tocreate a meaningful histogram. It has been determined that a period ofat least ninety days is sufficient if a user accesses regularly. After asufficient period of time, a Client Histogram can be built to determinethe probability of success of the user 110 connecting to the network thefirst time. This minimizes the necessity of having the client dispatchapplication 500 perform a second dial-attempt to connect to the network100.

The Server Histogram data is based upon the connection history of eachparticular ISP 102 and its dial-in numbers. This information is storedin the access service 106 in response to the monitoring of all the users110 (through the “pinging” process). The Server Histogram data istransmitted to the user's network services database 206 upon anyconnection to the network 100 when the availability sub-function isenabled within the client dispatch application 200.

In the preferred embodiment, the Server Histogram data is normally usedin conjunction with the Client Histogram data (when appropriate) todetermine the highest probability of success of connecting to thenetwork 100 without a second dialing attempt. Accordingly, upon the user100 initiating a connection to the network 100, the client dispatchapplication 200 automatically selects a dial-in phone number that it hasdetermined to have a high probability of success for connection. Thus,the Client Histogram data and the Server Histogram data are used tofacilitate a statistical approach to determine the highest probabilityof a user 110 connecting to the network on the first attempt.

However, there may be times when a user 110 desires a very highconfidence (near 100% or 100%) connection, or the Histogram data is notdesired to be used, such as when the data for a particular area isunreliable (i.e. certain geographic areas may have insufficienttelecommunications infrastructure that may skew the data) and thereforepossibly useless. In these cases the service selected sub-function isinitiated and a “double dial” process takes place (see FIG. 7 and thedescription of service selected sub-function). In the service selectedsub-routing, availability information of ISPs 102 is used by the accessservice 106 to give the user 110 a dial-in number that is available.This availability information for the ISPs 102 is periodicallytransmitted or given to the access service 106, typically every fiveminutes. The “double dial” process is also exemplified in FIG. 7 and theaccompanying text.

The last sub-function of the multi-dial procedure 700 is the“Single-dial Multi-Login” sub-function. Initiation of thesingle-dial/multi-login sub-function requires a “multi-dial” attemptonly when the user 110 receives a busy signal; otherwise thissub-function is a single-dial function with a multiple PAP ID and PAPpassword assignment/reassignment function. This function (theassignment/reassignment) requires that all user (client) 110authentication for all ISPs 102 happens at the access service 106 (i.e.,all authentication for all ISPs is centralized) or at a centrallylocated database point. Thus, this function works with multiple ISPs 102when each allows user authentication to take place at a centrallylocated server independent of each ISP's own user authentication server.For example, an ISP that has its own Authentication Server, and whoresells the underlying ISPs modem access to a user 110, may support thisfunction by allowing a user 110 to dial and connect using an “InitialAccess PAP ID and PAP password”, then assigning a unique session PAP IDand PAP password and “re-logging” into the Authentication server withoutdisconnecting the user 110. This eliminates the time that wouldotherwise be required to disconnect and re-dial using a newly assignedPAP ID and PAP password.

The client dispatch application 200 also functions to provide users 110with network identity anonymity. That is, the architecture of the clientdispatch application 200 provides anonymity for users 110 during accessto the network 100 as IDs and passwords (such IDs and passwords wouldinclude PAP IDs and PAP passwords, Email IDs and Email passwords, NEWSIDs and NEWS passwords, FTP and Web Space IDs and passwords, and customnetwork application IDs and passwords) can be dynamically reassigned fora given user, a given system, a given group of users, a given group ofsystems, or any combination thereof. Thus, if a user 110 has threecomputer systems (A_Computer, B_Computer, and C_Computer) each requiresa unique user/system identification which is generated duringinstallation and registration and stored in the client's network servicedatabase 206 and/or the user database 204. This unique user/systemidentification allows the access service 106 to maintain unique andindependent IDs and passwords for the user/system pair. Thus, when auser 110 connects the A_Computer to the network, unique IDs andpasswords which may be distinctly different from the B_Computer andC_Computer's IDs and passwords (stored in the network services database206 and/or the user database 204) may be used to transparently log theuser into such things as the network, Email, FTP/Web Space, NEWS groups,Bulletin Boards, or any other application requiring login identificationand password. Thus, the architecture supports single life IDs and/orpasswords for all network and application logins.

Now referring to FIG. 9, there is illustrated a block diagram of astorage medium 900 and a computer 902. The storage medium 900 includesclient dispatch application 200 (computer program) and may also includethe databases 204, 206, 208, 210. The computer 902 also includes a means(not shown) for reading or downloading the client dispatch application200 (computer program) into the computer 902 to cause the computer 902to perform one or more steps in accordance with the principles of thepresent invention. As will be appreciated, the storage medium 900 mayinclude a floppy or hard disk, magnetic or optical taps; or any otherdata storage medium known presently or developed in the future forstoring a computer program, such as the client dispatch application 200of the present invention.

As will be realized by those skilled in the art of email (electronicmail) sent between parties on a network, email is typically held in apost office box type storage facility at the recipients ISP untilretrieved by the recipient. However the ISP typically keeps a copy ofthe email for a period of time after receipt thereof for variouspurposes. Many people have the technical capability to access and readthese stored messages at the ISP. Even where the message body isencrypted, considerable information may be gleaned over a period of timeby keeping track of who is sending messages to whom, the frequency ofmessages to given parties and data gleaned from the subject matterportion of the header.

The structure of the present invention combined with an email program,software plug-in for a standard email program or browser lends itself toa method of minimizing the possibility of unauthorized gleaning ofinformation from email and further minimizes the possibility of spammingwhere spamming is defined as the sending of large amounts of email to agiven recipient for harassment like purposes.

One way to minimize the gleaning of information is to send all mailthrough a third party to recipients. The third party acts as a trustedbanker or broker. Such an operation is shown diagrammatically in FIG. 10where the sender sends the email to a Broker. The broker repackagesemail as deemed appropriate by agreement with the sender and/or therecipient and sends it on its way. The simplest form is to merely placethe entire original message including header information in message bodyof the email and send the package to the recipient with the recipientalso listed as the sender and placing an innocuous subject in thevisible header.

A next level of security is for either the sender or the broker or bothto encrypt the package sent by that party to the next party. This couldresult in double encryption of the message body. Similar plug-insoftware comprising part of the recipients email program, softwareplug-in for a standard email program or browser may be used to decipherthe received package and the original email would then be recreated forreading by the recipient. The deciphering may be accomplished by keystransmitted by the pinger entity to the recipients software. As part ofthis next level of security, the email sent to the broker or third partyin a preferred embodiment of this invention has the TO and FROM portionsof the visible header listing the broker, has the subject changed toinnocuous data and the entire original message encrypted as shown in thedrawing.

FIG. 11 presents the above process in a slightly different format wherea row labeled 1010 illustrates the original message composed by thesender. Either the sender of the plug-in software may then provide afirst level of encryption to the data as shown in row 1012. Transparentto the user, the plug-in software then repackages the original messageby encrypting the entire message and generating a new header with thethird party (here the third party is listed as NetSafe) listed as boththe sender and the recipient. The email sent to the broker is labeled1014. Since the broker is in contact with the data bases in the plug-insoftware via the pinger entity, the broker may decipher to second layerof encryption to determine the destination address. The broker may thenre-encrypt and send the email 1018 if the recipient is also a client ofthat broker and/or has similar plug-in software in contact with anetwork pinger. Otherwise, the originally composed, and possiblyencrypted, message is sent to the recipient as shown by the labeledmessage 1020

There may be times that the sender of email may not want the recipientto know the senders true identity or even the network service providerof the sender. Alternatively, the sender may wish to use differentaliases or names for different classes of email contacts so that thesender may quickly sort incoming mail into a set of priority stacks.Further the recipient of email in a system using the present inventionmay have similar requirements. FIG. 12 illustrates a second orderanonymity header process for email transmission.

In this figure a block 1040 represents a standard header of emailcomposed by the sender. When the sender has completed the email andposts it, the senders email program, software plug-in for a standardemail program or browser plug-in intercepts the email and checks theappropriate database. It is determined in block 1042 that for identity“me@other.com” the address “alias@galias.com” should be used. Theplug-in software thus creates a new header in substitution for the onecomposed by the sender and encrypts the entire message including thealtered header as shown in the lower portion of block 1046. The softwarethen consults the database represented by block 1048 and determines thatthe most recent data received from the pinger entity suggests that thenetwork service provider to be used for “other.com” in this instanceshould be “netsafe.com”. Accordingly, a new anonymous header is preparedin accordance with that shown in block 1046 before the message isforwarded to a third party for retransmission to the recipient.

As shown in FIG. 13, the third party or broker receives the email asrepresented by block 1060 where 1060 is identical to block 1046. Thesoftware in the server of the third party, as set forth in block 1062,decrypts the stored header information after noting the form of thevisible header information. It is able to do so because the pingerentity that determines the encryption code to be used in the sendersencryption process and provides the senders database with the thirdparty to be used, also informs the third party the encryption code to beused for deciphering. This code may be part of the visible message id ormay be inserted in the server database of that specific third party. Ifthe recipient has signed up for anonymity service, the server willretrieve from its database a presently assigned alias for the recipient.Whether or not an alias is used for the recipient, the third partyserver will rebuild the header using an address for the recipient inboth the TO and FROM portions of the visible header as shown in block1064.

FIG. 14 presents a block 1070 representing a received email as retrievedfrom the server storing email for alias.com. This message is identicalto the previously designated block 1064. The recipients software checksthe database and in accordance with block 1072 deciphers the message andcreates the viewable header set forth in block 1074.

FIG. 15 shows a sender composed message designated as 1080 and a partialrepresentation of a sender computer stored database 1082 along with arevised message 1084 wherein block 1084 corresponds with previouslydesignated block 1046 in FIG. 12. The software checks the database andnotes the subscript 1 for the server listed as “npn.net” in theregistered email domain portion of the database. The same subscript ischecked under the SECURE/EMAILDOMAIN portion to determine whether or notto encrypt the message, the encryption code whether or not to use athird party and if so the address to be used. As may be observed by thearrow lines, for npn.net, a PGP encryption is to be used, a broker is tobe used and the broker listed with a subscript “1” is “netsafe.com”.Thus “netsafe.com” is inserted in the visible header of the messageshown as 1084. The database also specifies the public key to be used forthe encryption and deciphering processes. The NO in the third to thelast line of the illustrated database 1082 provides an indication thatthe sender wants the recipient to be advised of the senders name ascomposed on his computer. This is in contradistinction to that shownFIG. 12 previously. When the server 1086 receives the message 1084, itwill consult a database similar to that illustrated as 1082 and performthe functions set forth in FIG. 13

The generation of software for intercepting a message, consulting adatabase, altering header data in accordance with the database,encrypting the entire message including the altered header and thencreating a new header before sending the entire data package is wellwithin the capability of anyone skilled in the art of network computerprogramming in view of the presentation in FIGS. 10-15 and theaccompanying explanatory material. As will be apparent, the softwarewill be different for each different operating system email program,software plug-in for a standard email program or browser and thus nopseudo code or detailed flow diagram has been presented herein.

FIG. 16 provides a simplified example of a button bar, power bar, ortool bar that can be generated using the referenced MOT script languagein combination with data retrieved from the data bases. If a client weretraveling away from home and accessed the network from New York, thisinformation would be provided to the pinger entity. If the client thenlogged onto a web page of an airline who was also a client of a serviceusing the present inventive components, the web page could beprogrammed, since data would be available that the clients home was forexample Dallas Tex., to immediately bring up a list of all flightsleaving New York and bound for other destinations that the client hadregularly traveled to in the recent past such as Dallas. The MOTgenerated bar or graphic in one implementation including a movingdisplay. Such a display may provide advertising or information liketicker tape like stock market data.

In FIG. 17, an illustrative commentary is provided of the databases andtheir contents upon initial installation of software of a new clientwishing to access the services of the present invention.

In FIG. 18 a selection menu 1102 is representative of a display thatwould be presented upon a clients system for selecting a test locationto initially use the software installed in FIG. 17. The phone databaseis represented by 1104 while the NS (network services) database isrepresented by 1106. When the client selects a city in Texas such asPlano, the software will note the number “1” at the end of the data ofdatabase 1104. In the NS database a “1” is shown to refer to UUNETservices. As may be observed, if Garland had been picked, a “2” wouldhave been detected and PSINet services would be used. As shown by arrowline 1108, the software would determine that the test location number is“519”, the PAPID to be used is “nsTEST” and the PAP password is“zzzwww123”. Other data that may be utilized is also contained in thedatabase.

In FIG. 19 the clients computer is designated as 1120, the network as1122, the network access provider as 1124 and the pinger entity as 1126.The test and update procedure is illustrated. The first action is for1120 to connect through the NAP shown within network cloud 1122 to 1124using the PAPID and PAP passwork in the NS database for the selectedNAP. As set forth in FIG. 18, these values would be “nsTEST” and“zzzwww123”. The NAP 1124 validates or authenticates the ID andpassword. For security reasons, the test ID and registration ID networkconnection, in a preferred embodiment of the invention, is limited to 90seconds. The system 1120 initiates a full network protocol test to thepinger 1126 by sending information about the client's system (1120) andthe software revision installed therein. As will be realized, theinstalled database includes the address of an appropriate pinger 1126.The pinger 1126, after receiving the information, performs minimalprocessing on the received data and sends back any update informationsuch as DNS changes, Phone number updates and the like. The pinger maythen send back some static information as well as any further updateinformation that the system 1120 may require. The client software in1120 checks the static information received, validates a reliableconnection and then processes any update information for storage in anappropriate location(s).

FIG. 20 is presented to help in the description of client registration.The clients system 1150, connects to an NAP in the network 1152 usingthe registration PAPID and PAP password stored in the NS database for aselected NAP as provided in the originally installed software. Such datamay be found in the appendix A NS database in the appropriate linesRAM/ACCT/REG. The authentication portion of the NAP (1154) validates thePAPID and PAP password so that the client 1150 may communicate with apinger entity such as 1158. (Although the preferred embodiment of theinvention has the client 1150 send a registration request to pinger 1158to provide further “security by obscurity”, the registration request canbe made directly to a registration and authentication server such as1156 if so desired and thus proceed directly to a later portion of thisparagraph description.) When pinger 1158 receives the registrationrequest, it returns addressing, ID and password information to client1150. This information will normally have a single life (that is it mayonly be used once) since the inventive system is designed to continuallychange passwords and other data such as addresses. With thisinformation, the client 1150 may now initiate a registration request tothe server 1156 as referenced above. The server 1156 processes the userssupplied information and issues a unique authentication token, atemporary PAPID and PAP password and/or a permanent PAPID and PAPpassword in accordance with system design. In an alternate embodiment,only a unique authentication token may be issued wherein the software inclient 1150 is required to obtain the PAPID and PAP password from apinger such as 1158. This supplied user registration information isstored in an appropriate database in 1156 for later authenticationpurposes. It may be noted that blocks 1156 and 1158 may share the samephysical hardware but may also be remotely located and be interconnectedvia the network.

FIG. 21 is similar to FIG. 20 in having a client system 1180, a network1182, a NAP authentication entity 1154, and a pinger entity 1186. Inaddition an optional PAP ID server 1188 is illustrated connected to theblocks 1184 and 1186. This connection may be through the network ordirect as illustrated in the drawing. A further plurality of blocksrepresenting at least a web server 1190, an email server 1192 and acommerce server 1194 are shown connected to the network and directly topinger 1186. When operating in a general or anonymous access mode, theclient 1180 connects to a NAP within network 1182 using a PAPID and PAPpassword assigned and stored in the NS database for a selected NAP. TheNAP validates the ID and password via block 1184. Once connected, client1180 initiates a “Network Presence Notification” to the appropriatepinger such as 1186. If the client 1180 is set in a selectable“Anonymous Mode” the “Network Presence Notification” will include arequest for a new alias along with revised PAPID and PAP password datafor use in the next network login attempt.

When the pinger 1186 receives the notification, the date and time ofreceipt in logged along with the clients authentication token and thenetwork address assigned to the client 1180 by the selected NAP. Thepinger 1186 returns a response which may, from time to time, include anew authentication token in addition to data requested when the clientis in the “Anonymous Mode”. It should be noted that the pinger entitiessuch as 1188 may be used to facilitate “Client side Authentication” whenused in conjunction with servers such as 1190, 1192 and 1194 asexamples. The client, or others attempting to access the system, doesnot have access to the information contained in any of the clientdatabases and the client and others cannot spoof a commerce server intobelieving that a transaction is originating somewhere else or by someoneelse.

From the above discourse, it may be appreciated that the variousdatabases residing at the access provider and each of the clientssystems along with a script language such as MOT and the two waycommunication between clients and an access provider permits dynamic orconstantly changeable network access and encryption parameters tominimize the possibility of unauthorized access to the network accessprovider or its clients communications. This is accomplished by:

-   1 Dynamic network login ID and password;-   2 Dynamically assigned network address;-   3 Dynamically assigned resource user Ids, passwords and so forth;-   4 Dynamic encryption algorithm use; and-   5 Dynamic encryption key generation and use.

With respect to item 1 above, since a user's network login and passwordchange periodically transparent to the user client and they are hiddenfrom the user so as to be not accessible by the user, network fraud andabuse may be significantly reduced. Further the dynamic assignmentprocess allows the login access to be different from system to system.Since the physical address of a server can be changed on any random orperiodic basis, Item 2 causes a significant reduction in the risk ofservice attacks, network lockouts and unauthorized access to data. Thedynamic assigning and reassigning of email alias as occurs in accordancewith Item 3 significantly reduces the risk of unauthorized viewing of agiven clients email messages. The changing domain aliases minimizes therisk of denial of access service while the dynamically generated andauthenticated session IDs for network commerce reduces the risk offraud.
